MODIFIED PHASE SHIFTED GATE DRIVE

A modified phase shift scheme that provides the minimum on-time and regulation benefits of the conventional phase shift method with the reduced circulating current benefits of the traditional PWM control. A welding machine comprises an inverter operatively connected to a controller, wherein the cont...

Beschreibung
Zusammenfassung:	A modified phase shift scheme that provides the minimum on-time and regulation benefits of the conventional phase shift method with the reduced circulating current benefits of the traditional PWM control. A welding machine comprises an inverter operatively connected to a controller, wherein the controller controls a welding process of the welding machine using modified phase shifted switching of the inverter.
